[R] change individual label colours in a cluster plot?

[Sur Nathan]

Hi Jim,

  How are you?  I saw your posting. I am trying to do clustering for co
authorship.What I have is undirected graph .I want to have clusters for 393
nodes.

I am attaching the file along with this mail.If you move to the section
Cluster I am looking to do something like that.Is it something you are
familiar with.

Can you tell me how you did it in R. 

Nathan
